with llc on i got more vcore then i set in bios usualy. Iv never really used it with llc off cause my idle vcore would make me run hotter when idle.

Your temps are right there on the hot side. 71.4c is the max recommended by Intel, I believe. (Forgot you had a quad...may be different)

memtest86+ is good to see if the RAM is stable at the speeds/timings/voltages you are using. Run it one stick at a time. That way you can see, individually, if they are going to run smoothly.

Now run a blend and see if the whole thing (cpu/MCH/RAM) is stable. 8 hours.

If you pass that your 4GHz is a stable oc. If not, you know it's the RAM/north bridge that need tweaking.

After that you can see if you can get a stable at a slightly lower vcore. It's possible.

Good job. You're putting in some good work there bro.
That's the frustrating thing...I ran small fft's for 10 hours like you said yet if I run large fft's it fails within 2 minutes...weird huh? I originally had MCH and CPU term at 1.3 each but have tried each at 1.32/1.34 in all combinations...I keep thinking it may be the MCH/CPU refs but am not getting anywhere...I don't have the DRAM ref setting and a couple others though in the bios...

It's weird that 3.92GHz is rock solid but 3.94GHz fails large fft's in 2-3 minutes...I've tried bumping up vcore a few notches too but it still fails just as quickly...I have also tried the 333 and 400/B straps...how big can a "fsb hole" be...should I try something like 475fsb?

Don't worry man, I do it all the time too. Most of the time though people know exactly what you mean anyway.

ET6 can be handy for 'testing' out small settings changes that you would afterwards go back and enter into bios. For ex. playing w/ cpu/nb ref. voltages goes a lot faster when you don't have to reboot ever single time you want to give it a nudge. Of course though once you find it you'd go back to bios for the permanent setting.

pdawg17 I don't think your fsb is high enough to have to mess with the refs. Only time I've seen people have to really mess with those is at 500fsb or very near it. Try setting your refs to Normal in bios.
CPU Ref [Normal]
MCH Ref [Normal]

Your MCH voltage should be good at 1.28/1.30. People at 500+ fsb run those voltages just fine. Of course all hardware is unique but that's a good baseline.

At the settings you ran last night, run a blend test. You passed 10 hours of small fft's, that's good. See how the blend goes. (Don't worry about large fft's right now.) Maybe you're failing large because you wouldn't pass the blend test.

So leave your vcore at 1.32 (CPU-Z)
cpu term:1.3
MCH: 1.28/1.30
CPU Ref [Normal] <-- if it fails try these on [Auto] next.
MCH Ref [Normal]
Get your RAM as close to stock settings/timings/voltages as you can and run the blend test.

Let's see how that goes. Let's see if it passes a blend test. If not, see how long it runs and maybe it'll just take that one tweak to get you there.

8 hours.

I know it seems long and all but, to avoid corrupting things on your computer it's necessary bro. Just watch those temps. You are already right there...70c is pretty hot. Don't get frustrated, this is how we all learn. That's why I advised you, keep track of your voltages and all because this is your hardware and it's different from everyone else's. Learn it as you go to remove any guessing from future adjustments.

Good luck.

Edite: "should I try something like 475fsb?" Raising the fsb could possibly mean a whole new combination of settings. Get what you have stable. When you do you'll be this close to 475 and should be able to manage it.

I basically just repeat what you, dennyb, supa, TwoCables, Acoma_Andy, grishka and others have tought me.

Had some awesome help along the way.

@richard, look at the connection, are any pins bent or anything? Have a peak in there.
